Abstract :
Receiver electronics dominate power consumption in coherent optical transmission systems. To break this bottleneck, we propose a receiver based on analog domain signal processing and Costas loop. System simulations show that laser linewidths as high as 3 MHz can be tolerated, making it ideal for low cost short range applications such as data centers.
